FMraadiovastuvõtjad

FMraadiovastuvõtjad, also known as FM radio receivers, are electronic devices designed to detect and amplify radio waves in the FM (Frequency Modulation) broadcast band. This band typically spans from 88 to 108 megahertz in most parts of the world. The primary function of an FM receiver is to convert these invisible radio waves into audible sound.

The process begins with an antenna, which captures the radio waves. These waves are then passed through a tuning circuit, allowing the user to select a specific radio station. Once a station is selected, the signal is amplified. FM receivers employ a process called demodulation to extract the audio information from the modulated radio frequency carrier wave. This demodulation is crucial because in FM, the audio signal is encoded by varying the frequency of the carrier wave, unlike AM (Amplitude Modulation) where the amplitude is varied.

Modern FM receivers often include features such as digital tuning, presets for storing favorite stations, and stereo sound capabilities. They can be found in a wide range of devices, from standalone radios to car stereos and portable music players. The clarity and fidelity of FM radio, due to its inherent resistance to static and interference compared to AM, has made it a popular medium for music and talk radio broadcasts.
